Overview

Plywood is usually thinner than the nominal measurements indicate. As a result, regular size bits usually don't cut a tight-fitting dado. Fortunately, undersized dado bits like these will help your joinery fit perfectly, resulting in stronger assemblies and nearly invisible joint lines. This set includes the three most common sizes of straight bits for undersized plywood: 23/32" for 3/4" plywood, 31/64" for 1/2" plywood, and 15/64" for 1/4" plywood.

I'm hoping these sizes will fit my plywood sizes purchased from Lowes/Home Depot better than the standard size router bits I already have. Saves time making adjustments and making jigs to fit undersized plywood.

Got these for ease in cutting the dados needed for plywood. I'm very pleased that they are sized right. I continue to used my stacked dado on the table saw for some applications, but these are very good.

I used these bits to make a plywood box with dividers. I used 1/2 and 1/4 inch plywood. I used the bits to make slots for the dividers and to make a channel for the box bottom. The plywood fit exactly within the slots and channel with no extreme tightness and no substantial play. I was extremely happy with the fit.

I've always made too passes with a narrower bit. These are a big time saver. One thing I would point out.... to the writer of the ad: Its not "undersized" plywood, it is Metric plywood. 3/4 ply is typically 18mm plywood because it is all imported... so even these bits are a touch too large. I haven't been able to find a set made for MM measurements and I am not a big fan of the visible joint these create... But I won't deduct a star for that.
